It's really intriguing the way you use the word 'you' as if you're inviting the reader to be fully active in the story, as if they have a role to play. You're description is also very magnetizing, the first sentence and I was drawn in, ready to know more.
You do a good job of making this character alive because you give her aspects of feeling that a normal person has. You mention at one point that I couldn't have told her the world was ending, because that would break her. I feel like the character wanted a sense of distraction or was oblivious from what was going on around her and if she suddenly became aware, she wouldn't be accepting of the news which I think is a perfect trait. You make her well rounded because she's naive and the way you're wording it it's making it seem like, to tell her would break both my heart and hers.
The whole 'the world is ending' thing intrigued me. Maybe you want to leave it as a mystery, but I think if you mentioned how or why, the cause, towards the end, it may help your reader understand the circumstances. Or, a mystery works just as well.
I feel like this novel may take place in a dystopian world or apocalyptic world, and you made this clear by stating the waste lands and the very obvious- the world is ending. You could make the setting stronger by providing senses (see hear touch etc) if you wanted. Or it could be symbolic for the world we're living in now, which I also think is a great thing, maybe include hints to help the reader know what time period it's in.
Your use of figurative language really pulled me into the story, I didn't find it boring or long at all, I was actually hooked from beginning to end, which is a good thing.
This is a really great excerpt, your writing style is very descriptive and you really give the reader a sense of what's going on and what the character is feeling, along with a threat, if she were ever told what actually happened, she would be crushed, and no one wants that.
